What's New / NOTES
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Tuesday..Southwest winds 5 to 10 knots increasing to 15 to 25 knots. A chance of snow showers. Wednesday..Southwest winds 5 to 15 knots. A chance of snow showers during the day, then snow showers likely Wednesday night.Thursday..Northwest winds 5 to 15 knots. Snow showers likely during the day, then a chance of snow showers Thursday night. The saint lawrence seaway has closed to navigation for the season, therefore the forecast for the saint lawrence river has been discontinued. The forecast will resume in the spring when the river opens for navigation.

Synopsis
High pressure remains well entrenched across the north country.

Persistent northwesterly flow will keep unseasonably cold and
dry weather over the north country through midweek. A coastal
low will strengthen Wednesday as it moves from the carolina
coast northeastward. The brunt of the impacts with this system
still look to be to our south and east, however we can't rule
out some light precipitation over areas of vermont Wednesday
and Thursday.

Near term through Tuesday night
As of 730 pm edt Monday... Going forecast in real good shape and
no big changes needed at this time. Based on satellite satellite
trends tempered back a little on the sky cover as it now looks
like clear mostly clear conditions for the remainder of the
night. Rest of forecast remains unchanged.

Previous discussion...

high pressure continues to build across the north country this
afternoon. Clear skies have been observed across the region
thanks to subsidence associated with the high pressure and
precipitable water values ranging from 0.05 inches to 0.10
inches. Gusty winds will continue through the afternoon hours as
steep surface lapse rates have set up with temperatures warming
into the 20s and 850 mb temperatures still in the -13c to -15c
range. Once temperatures start cooling around sunset, the
boundary layer should quickly decouple and gusty winds will
quickly come to an end.

Temperatures tonight could be a little tricky as a diffuse
shortwave is slated to track across the region. Given
precipitable water values 0.10 inches or less, it's difficult to
imagine and precipitation will be squeezed out. However, there
is the potential for some cirrus to move over the region between
06z and 12z on Tuesday which may inhibit radiational cooling.

However, at this moment, the shortwave looks rather unimpressive
on both water vapor imagery and visible imagery which leans the
forecast away from any cloud cover during the overnight hours.

That being said, temperatures will once again be well below
normal tonight but should be a few degrees warmer across the
board than the past several night as the air mass continues to
modify. 850 mb temperatures continue to warm with models
progging temperatures warming from -15c this afternoon to -7c
by this time tomorrow. Temperatures in saranac lake will drop to
around -10f tonight while most other locations will remain in
the single digits to lower teens.

Wednesday will see temperatures warming into the upper 20s to
lower 30s as temperatures off the surface continue to warm.

Winds should be light as less mixing is expected with warming
elevated temperatures and the low level jet at 850 mb weakens.

Short term Wednesday through Wednesday night

As of 245 pm edt Monday... No real change in the forecast in
regards to the potential impact from another coastal low
developing off the carolina coast early Wednesday. While model
trends are hedging a tad further north, the consensus low track
remains south and east of the benchmark with the best deep layer
moisture and lift well southeast of the north country. Will
offer a slight increase in pops in the southeast corner of
windsor county Wednesday evening night but still only in the
chance category with perhaps a dusting to an inch of light snow
possible by Thursday morning. Elsewhere, partly cloudy skies
will persist through the period with only a slight chance of
light snow and or flurries with no accumulations expected at
this time. Temps will remain well below normal with highs only
in the upper 20s to low 30s and lows in the teens to mid 20s.

Long term Thursday through Monday
As of 245 pm edt Monday... Overall large scale pattern through
the end of the week and much of the weekend will feature a broad
upper trough over the northeast with bits of shortwave energy
moving generally south of the area as high pressure to our north
keeps the region dry. The result is mainly partly to mostly
cloudy skies, temps below normal in the 20s and 30s, and maybe a
few mountain snow showers. Heading into Sunday and Monday, an
amplifying upper ridge over the central CONUS will look to shift
over the northeast with some sunshine and closer to normal
temperatures possible.

Aviation 00z Tuesday through Saturday
Through 00z Wednesday...VFR conditions will persist through the
forecast period as high pressure remains over the area. Little
in the way of any cloud cover will exist as a result and winds
will generally be under 10 knots through the period.
